KEY MESSAGES

- An unseasonably mild weekend is ahead of us, with dry conditions expected.

- Unseasonably mild temperatures will remain into next week, with precipitation chances increasing mid-late week.

SHORT TERM /THROUGH SUNDAY NIGHT/

Issued at 155 PM CDT Fri Oct 9 2026

Weak ridge will pass overhead tonight and east of the area tomorrow, with the warm front and associated precipitation off to our northeast. As the weak ridge passes east of the area Saturday, broad southwesterly flow will set up overhead as Isaias moves farther inland and a wave deepens over the Rockies. This will set the stage for warm advection into the region, with a stronger ridge developing overhead Sunday into Monday. Overall, we are in for a quiet weekend, weather-wise. This pattern will favor temperatures well above seasonal normals, with Saturday geared to be the warmest day this weekend. Widespread temperatures in the low-mid 80 can be expected Saturday, with increasing mid-high clouds associated with Isaias through the day. The increasing cloud cover may limit how warm some locations get through the afternoon. Aside from a southerly breeze with gusts upwards to 20-25 mph through the afternoon Saturday, it will be a mild and pleasant fall day. Sunday will feature decreasing cloud cover, with temperatures increasing into the upper 70s to low 80s.

Enjoy the beautiful weekend!

LONG TERM /MONDAY THROUGH FRIDAY/

Issued at 155 PM CDT Fri Oct 9 2026

The ridge that started to build overhead on Sunday starts to flatten out at the start of the work week, as a deep wave strengthens over the Rockies and guides weak shortwaves through the region. This will leave us with upper level zonal flow through Tuesday, with the aforementioned deep wave forecast to eject off of the Rockies Wednesday/Thursday. At the start of the week, llvl winds will be out of the southwest, resulting in moderate warm advection into the area. Mostly dry weather will be seen due to lower moisture, with above normal temperatures favored to continue until at least mid week. As was mentioned above, weak bouts of energy will pass overhead ahead of the stronger wave, largely bringing a brief wind shift and passing clouds. Monday will be another day of unseasonably mild temperatures in the mid 80s for many, with temperatures in the low-mid 70s Tuesday behind a passing system.

Tuesday night and through the remainder of the week, an active pattern will take shape when the deeper wave ejects off of the Rockies and tracks northeast through the region. Stronger warm advection (35-45+ KT 850 hPa jet) will kick in ahead of this wave, favoring increasing moisture throughout. With plenty of forcing and moisture in place, widespread showers/storms will be seen. The timeframe that guidance is currently highlighting for the more widespread convection will be Wednesday night through Thursday. There remains some uncertainties on further details at this time, along with it being too soon to determine any severe or flash flood threat. Thus, stay tuned for future updates. Temperatures during this timeframe will be a little lower and closer to seasonal normals, as we will be largely blanketed in clouds.

After this system passes, guidance is in agreement on a seasonally strong cold front crashing through the region late in the week, bringing cooler and dry air.

AVIATION /00Z TAFS THROUGH 00Z SATURDAY/

Issued at 606 PM CDT Fri Oct 9 2026

Clear skies will generally continue through the period below 20kft, with some increase in high clouds possible at times Saturday as the cloud shield aloft from the landfalling hurricane brushes by the area. Light southeast winds will turn a bit more south through the period. A lower end period of Low level wind shear remains possible this evening, near DBQ, with surface winds southeast, and winds aloft are southwest at 30-40kts 2K feet aloft.
